Vertebral artery transection: a unique deadly safety belt harm.
11mm and 0.12mm for both scalae. The mean distance between the centroids for the round window was 0.32mm, and the mean AVG HD was 0.09mm. The mean distance and angular rotation between the mid-modiolar axes were 0.11mm and 9.8 degrees, respectively. Visually, the segmented structures were accurate and similar to that manually traced by an expert observer.
An atlas-based approach using 3D micro-slicing data and affine spatial registration in the cochlear region was successful in segmenting cochlear microstructures of temporal bone anatomy for use in simulation software and potentially for pre-surgical planning and rehearsal.

SAH is a life-threatening emergency and a relatively common entity, the most common etiology being ruptured aneurysms. Multiple conundrums exist in literature at various steps of its imaging workup diagnosis, management, and follow-up. We target our review to highlight the most effective practice and suggest efficient workup plans based on literature search, and describe in detail the clinical diagnostic and prognostic scales, role of CT scan, lumbar puncture, and MR, including angiography in the diagnosis and workup of SAH and its complications, and try to simplify the conundrums. Practical knowledge of imaging workup of SAH can help guide correct management of these patients, so as to reduce morbidity and mortality without resource overutilization.
To describe the clinical presentation of trauma patients receiving a negative cervical spine MRI (CSMRI) after cervical spine CT (CSCT) without acute findings and calculate the associated costs.
Our cohort consisted of 55 retrospectively reviewed consecutive trauma patients with CSMRI performed between October 2016 and March 2020, who had negative CSCT within 7 days of CSMRI and no other clinically significant injuries. MG149 clinical trial Our outcome was the cost related to CSMRI, estimated by CSMRI charges and the charges related to additional hours of prolonged hospital stay from CT until MRI.
The most common presenting mechanisms of injury were fall from standing (20/55, 36%), followed by motor vehicle accident (18, 33%). Indications for CSMRI included persistent neck pain (32/55, 58%), followed by recommendation from the radiologist (12, 22%), and neurological symptoms concerning for spine injury (9, 16%). An average of 11.2 h (median 8.5, range 0.2-25.4 h) passed from CSCT to CSMRI. Fifty-four (98%) of the CSMRI examrces.
To determine the influence of periapical lesions on the repeatability of two electronic apex locators (EALs), Root ZX II, and RomiApex A-15, in maxillary anterior teeth, in vivo.
After approval by the local ethics committee, 43 maxillary anterior teeth scheduled for root canal therapy were assigned to two groups. The periapical lesion (PAL) group included 21 teeth with necrotic pulps and radiographically visible periapical lesion, and the normal periapex (NPA) group consisted of 22 teeth with vital pulps and no periapical lesion. In each canal, Root ZX II and RomiApex A-15 were used to determine working length defined as the "zero" reading on the display. Two consecutive measurements were performed with each EAL on each tooth and a second operator measured the endodontic file with a digital caliper without knowledge of the EAL being used or the tooth diagnosis. The absolute value of the difference between the first and second measurement (measurement pairs) was calculated. Repeatability was evaluated by the Bland-Altman method, and an aligned ranks transformation ANOVA was conducted to compare the EALs.
The median absolute difference between measurement pairs was significantly lower (p < 0.001) and the limits of agreement were narrower in the NPA group. Among the EALs, median absolute differences were significantly smaller for Root ZX (p < 0.001).
Measurements were more repeatable when no periapical lesion was present. Root ZX showed better repeatability than RomiApex.
Periapical lesions seem to influence successive in vivo measurements with EALs.

The recommended stroke prevention for patients with atrial fibrillation (AF) and increased risk of ischemic stroke is oral anticoagulation (OAC). Parts of the patient population are not eligible due to contraindication, and percutaneous left atrial occlusion (LAAO) can then be a preventive treatment option. The aim of this systematic review and meta-analysis is to estimate the long-term clinical effectiveness of LAAO as stroke prevention in patients with AF, increased risk of ischemic stroke, and contraindication to OAC.
We performed a systematic review and meta-analysis, using Poisson random effect models, to estimate the incidence rate (events per 100 patient-years) of ischemic stroke, transient ischemic attack, major bleeding, and all-cause death after LAAO treatment. We also calculated the risk reduction of ischemic stroke with LAAO compared with no stroke prevention estimated through a predicted risk in an untreated population (5.5 per 100 patient-years).
We included 29 observational studies in our meta-analysis, including 7 951 individuals and 12 211 patient-years. The mean CHA
DS
-VASc score among the patients in the included studies is 4.32. The pooled incidence rate of ischemic stroke is 1.38 per 100 patient-years (95% CI 1.08; 1.77). According to a meta-regression model, the estimated incidence rate of ischemic stroke at CHA
DS
-VASc 4 is 1.39 per 100 patient-years. This implies a risk reduction of 74.7% with LAAO compared to predicated risk with no stroke prevention.
Our results suggest that LAAO is effective as stroke prevention for patients with AF, increased risk of stroke, and contraindication to oral anticoagulation.
